It is hard to guess what a Black-spined Atlantic tree-rat weights. But we have the answer:
An adult Black-spined Atlantic tree-rat (Phyllomys nigrispinus) on average weights 224 grams (0.49 lbs).
The Black-spined Atlantic tree-rat is from the family Echimyidae (genus: Phyllomys). When reaching adult age, they grow up to 21.3 cm (0′ 9″).
